No. You have to launch all Apps through the home screen (Springboard).

There might be a way to do this when jailbreaking the device, though.

That same functionality, which you speak of, is exactly what runs on the iPhone BEFORE it is "activated". I wonder if there is a way to use this already built in app to create what you're shooting for.
